Brief summary
The purpose of this Phase 3 study was to determine whether iptacopan is efficacious and safe for the treatment of Paroxysmal nocturnal hemoglobinuria (PNH) patients who were naïve to complement inhibitor therapy.
Detailed description
This study was a multicenter, single-arm, open-label trial which was comprised of 8 weeks screening period, 24-week core treatment period and 24-week extension treatment period. Eligible PNH patients with hemolysis (LDH \> 1.5 ULN) and anemia (hemoglobin \<10 g/dL), who were naive to complement inhibitor therapy, including anti-C5 antibody treatment, received iptacopan monotherapy at a dose 200 mg orally b.i.d.
Interventions

Requiring RBC transfusions refers to any patient receiving transfusions or meeting protocol defined criteria (Hemoglobin level of ≤9 g/dL (≤8 g/dL for Chinese population) with signs and or symptoms of sufficient severity to warrant a transfusion or Hemoglobin of ≤7 g/dL (≤6 g/dL for Chinese population), regardless of presence of clinical signs and/or symptoms). The term 'marginal proportion' can be interpreted as the population average probability of being a responder. Results incorporated a method to handle missing data using multiple imputation. Hence, all 40 patients enrolled contributed to the primary analysis. |

| Change From Baseline in FACIT-Fatigue Score | Baseline and mean of visits between Day 126 and Day 168 | Change from baseline in FACIT-Fatigue scores as mean of visits between Day 126 and Day 168. The FACIT-Fatigue is a 13-item questionnaire with support for its validity and reliability in PNH that assesses patient self-reported fatigue and its impact on daily activities and function. All FACIT scales are scored so that a high score is better. As each of the 13 items of the FACIT-F Scale ranges from 0-4, the range of possible scores is 0-52, with 0 being the worst possible score and 52 the best. Change from baseline was analyzed using a Mixed Model of Repeated Measures (MMRM) which includes age (indicator variable of age ≥ 45 years), sex, history of transfusion (yes/no) prior to study treatment, visit, baseline FACIT-Fatigue score as fixed effects and visit\*baseline FACIT-Fatigue score as interaction. |
